The AirTAC GFR200-08 AirTAC Filter Regulator NPT1/4 psi Gauge is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR200-08 is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one compact body. This 200-size unit has 1/4 in NPT ports, a manual drain bowl, a 40 um standard filter element, a standard-range regulator adjustable from 0.05 to 0.9 MPa (7-130 psi), and an embedded square gauge scaled in psi. No mounting bracket is fitted and no reverse/check valve is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, a choice of manual, automatic or differential-pressure drains, a 5 um optional element, gauge scale options and G/NPT thread variants. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures for your application before ordering.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Filtering and regulating the shop-air feed to a CNC machine's pneumatic tool-changer and clamping circuits, with the square psi gauge giving the operator a direct pressure readout at the machine.
Conditioning the air feeding the valve island on a carton-sealing or wrapping line, where clean, dry, correctly regulated pressure keeps cylinder strokes consistent shift after shift.

Size and port step up together: 200/300/400/600, from 1/8 to 1 in, so pick the size whose flow curve covers your demand at your working pressure - we can check the curve against your application. Drain choice matters: manual (this unit) needs periodic bowl draining, automatic suits unattended points, and differential-pressure drains the bowl whenever the pressure drop across the filter rises. Filter grade is 40 um standard; choose the 5 um W element when downstream equipment needs finer filtration. Gauge scale is selectable (MPa, psi or bar), and PT is the standard thread with G and NPT as order options. Brackets are optional on this family; this configuration ships without one.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the correct size from the datasheet curves on request before you order.
Manual drain means someone opens the bowl drain periodically to expel collected water. The GFR series also offers automatic drains for unattended installations and differential-pressure drains that discharge when the filter loading rises - the drain type is part of the model code, so choose it when ordering.
